Why would the method in the left not work? Thanks

#

It will work

#

Integral of this fraction is 4sin....

#

So 1/4 x 4sin()...is same as the result on the right

#

Sorry I’m a little confused where the 4sin() comes from

#

I mean arsin

#

You wrote 1/4 * sin-1(x/4)

#

I am saying that it should be 1/4 * 4 sin-1(x/4)

#

Oh I see now cuz you want to cancel the 1/4

#

From the arcsin(x/4) correct
